Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-performance stainless steel fastening solutions for extreme service conditions. Their Stainless Steel 314 Nuts are engineered for applications requiring excellent resistance to high temperatures, oxidation, and corrosion. With a high chromium and nickel content, these nuts maintain strength and stability under continuous thermal stress. Manufactured with precision and strict quality control, Walid Stainless ensures accurate threading, durability, and long service life. Customers rely on Stainless Steel 314 Nuts for secure fastening and dependable performance in demanding industrial environments.
Stainless Steel 314 Nuts are produced from an austenitic stainless steel alloy containing approximately 24–26% chromium and 19–22% nickel. This high alloy composition provides superior resistance to oxidation and scaling at temperatures up to 1150°C. These nuts typically exhibit mechanical strength consistent with 314-grade fasteners and hardness around 170–200 HB. The austenitic structure ensures excellent toughness, weldability, and mechanical stability in high-temperature and corrosive environments.
